ALMOST DONE SECTION 2.0!

We are almost done learning about the material in Section 2.0. You should have read up to page 129 in your textbook by now; if not you are behind!

THIS WEEK:


  • Continue to learn about the structure of the atom
  • Completed work relating to chemical properties, the periodic table, etc.
  • Review assigned work, going over answers
  • Learning how to calculate how many neutrons are in an element using atomic number and mass number (see example below)

Example: How many neutrons does Carbon -14 have? Carbon -14 has a mass number of 14. You can determine how many neutrons Carbon 14 has because the mass number is the total of protons and neutrons and the atomic number is the amount of protons. So what we do is take the mass number (14) and subtract the atomic number (6) which leaves us with 8, the number of neutrons in carbon 14. This is a skill you need to have!

ASSIGNED WORK:

  • Reading the rest of secti0n 2.0
  • Complete new vocabulary (Vocabulary #7)
  • Review questions to ensure we have learned the contents of section 2.0: check and reflect page 121 (1-11), page 125 (1-7), page 134 (1-8) and Assess your learning (1-6 only) are Due Monday, November 23th.
